Need help with php increment ...

[AshleyQuick]

I believe it's called increment. Either way, I cannot figure out how to simply count up beginning at 1 (in red in the div below) ...

 

function wp_rss( $url, $num_items = -1 ) {

    if ( $rss = fetch_rss( $url ) ) {

        echo '<div id="charts">';

 

        if ( $num_items !== -1 ) {

            $rss->items = array_slice( $rss->items, 0, $num_items );

        }

 

        foreach ( (array) $rss->items as $item ) {

            printf(

                '<div id="chart_lt">1</div><div id="chart_rt">%3$s</div>',

                esc_url( $item['link'] ),

                esc_attr( strip_tags( $item['description'] ) ),

                htmlentities( $item['title'] )

            );

        }

 

        echo '</div>';

    } else {

        _e( 'An error has occurred, which probably means the feed is down. Try again later.' );

    }

}

increment is done with ++

in a loop, $count++; would increment $count + 1 for each loop.

 

function wp_rss( $url, $num_items = -1 ) {
    if ( $rss = fetch_rss( $url ) ) {
        echo '<div id="charts">';

        if ( $num_items !== -1 ) {
            $rss->items = array_slice( $rss->items, 0, $num_items );
        }
//start count
$i = 1;
        foreach ( (array) $rss->items as $item ) {
            printf(
                '<div id="chart_lt">'.$i.'</div><div id="chart_rt">%3$s</div>',
                esc_url( $item['link'] ),
                esc_attr( strip_tags( $item['description'] ) ),
                htmlentities( $item['title'] )
            );
//increment
$i++;
        }

        echo '</div>';
    } else {
        _e( 'An error has occurred, which probably means the feed is down. Try again later.' );
    }
}
